![]() The selected configuration incorporated flow field components with significant cost reduction potential in commercial cell applications. The cell configuration was further refined and a final configuration selected to support testing. Over the course of the 2-year Phase 2 program, significant progress was made in advancing electrochemical pump cell technology. The industrial collaborators provided test materials for the humidification plate which were incorporated into Proton cell designs for test. Significant performance improvement was demonstrated over the baseline cell in both two-chamber (no humidification plate) and three-chamber (with humidification plate) cell configurations. Proton collaborated with industrial partners to compare operating characteristics between two different cell configurations of a proton exchange membrane (PEM) electrochemical pump. d/b/a Proton OnSite (“Proton”) demonstrated feasibility of recycling and compressing waste hydrogen for high purity applications via an electrochemical pump. In Phase 1 of this project, Proton Energy Systems, Inc.

Advances in these areas would find immediate commercial interest, and address key strategic areas on the government agenda related to energy savings and green technology. The device proposed has the opportunity to decrease the energy required to produce pure hydrogen by 75% over generating additional hydrogen from water, and to compress the hydrogen with as little as 200 mV of overpotential even at high current density. Having a mechanical compressor that represents half of the size and material cost of a home fueling or backup power device is not commercially feasible. In applications where hydrogen is being evaluated as an alternative fuel, high pressure storage is needed. Current solutions for hydrogen compression are also noisy, bulky, and inefficient. Thus, significant energy waste is generated. Currently, increases in dew point cause significant decreases in cooling efficiency and increase windage losses by several percent, requiring purging of the hydrogen chamber and increased production to backfill. For example, over 16,000 power plants worldwide use hydrogen as a cooling fluid in the turbine windings. ![]() The broader impact/commercial potential of this project includes applications ranging from power plants to heat treating to backup power and fueling. The anticipated result will be an improved hydrogen recycler which will enable substantial reduction in hydrogen production cost and new market opportunities. The objectives of this phase also include additional test stand modifications to enable a broader range of test conditions, demonstration of gas purity through analysis to determine the separation efficiency, and development of system schematics and product requirements. Poison-tolerant catalysts will also be developed to enable a broader range of applications. In Phase 2, refinement of the microporous plate will be performed for optimal water distribution, which will enable more uniform fluid distribution and high current densities. In Phase 1, feasibility of operating a proton exchange membrane (PEM)-based device as a high efficiency electrochemical compressor/purifier was demonstrated at up to 3 A/cm2. This Small Business Innovation Research Phase II project addresses current limitations in hydrogen compression and enables reduction in hydrogen requirements for several applications through recycling of exhaust hydrogen containing water and other benign impurities.
